IS32LT3178 Datasheet | Lumissil

IS32LT3177/78 10-TO-200MA CONSTANT-CURRENT LED DRIVER FOR AUTOMOTIVE June 2024 GENERAL DESCRIPTION The IS32LT3177 and IS32LT3178 are adjustable linear current devices with excellent temperature stability. A single resistor is all that is required to set the operating current from 10mA to 200mA. The devices can operate from an input voltage from 2.9V to 40V with a minimal voltage headroom of 1.0V (Typ.) at 150mA. Designed with a low dropout voltage; the device can drive LED strings close to the supply voltage without switch capacitors or inductors. The IS32LT3177/78 simplifies designs by providing a stable current without the additional requirement of inductors, FETs or diodes. The...
